Chevy Bolt EV's battery shows big improvements over Spark's

Plug-in vehicle battery technology moves fast, and all you need to do to see this in action is to take a look at the new 60-kWh lithium-ion pack inside the 2017 Chevy Bolt EV. Well, you need to do that and then compare it to the battery packs inside of GM's other plug-in vehicles. And you don't even to go as far back as the EV1 to see progress. Let's start with what we know about the new Bolt's pack. It is supposed to drive the Bolt EV over 200 miles on a full charge. It weighs 960 pounds and is made up of 288 cells. Chevy's other all-electric car, the limited-availability Spark EV, had a 19-kWh pack and offered 82 miles of range. It had 192 cells and weighed 474 pounds. So, in the few years since the Spark EV was released, GM engineers have figured out how to get three times the energy capacity and almost two-and-a-half times more range out of a pack that weighs only about twice as much. And that doesn't even get to the price drops. GM has figured out how to get 3x the energy capacity and almost 2.5 times more range out of a pack that weighs only twice as much. Speaking of those 288 cells, that number might sound familiar to regular readers because that's exactly how many are in the new Chevy Volt. But the packs in the Volt and the Bolt are entirely different beasts. For one thing, while the Volt cells are made by LG Chem in Holland, MI, LG Chem will make the Bolt's cells in South Korea. The cell chemistries are also different. We spoke with GM engineer Tim Grewe (again) and while he declined to answer some of our Bolt battery pack questions until more details are unveiled at the SAE World Congress in April, he was able to explain a few things. "The cell inside the Chevy Bolt EV was specifically designed for EV range so it's up on energy," he said. "That's a different cell chemistry than on the extended range Chevy Volt, which is a smaller pack, smaller energy but more power per cell. We work with all of those vehicle requirements and customer demands and we say how do we meet this and we change the chemistry to make it all work." Comparing the 60 kWh in the Bolt and the 18.4-kWh pack in the Volt is really one of those apples to oranges issues, he said. "If you look at the Volt battery pack, how it went from where it was and where it's up to, from 38 miles to 50 miles, that was basic, overall industry improvement. Now, the 18 [kWh] to the 60 [kWh] is extended range vs. EV.

More than 5,500 people tried to get the 2016 Chevy COPO Camaro

It's stating the obvious, but the 2016 Chevy COPO Camaro is popular with enthusiasts. So much so, it's attracted more than 5,500 hand raisers, General Motors said Tuesday at an event to show off the company's new Performance and Racing Center in Pontiac, MI. Unfortunately for drag racing fans, Chevy will only sell 69 of them, as it has for the last four years. The COPO Camaro can be configured for the NHRA Stock and Super Stock classes. It comes with racing-tuned chassis pieces and a solid rear axle. Power choices include 5.7-, 6.2- and 7.0-liter V8 engines. About half of COPO Camaro owners race their cars, and the rest keep them as collectibles. Jim Campbell, GM vice president of Performance Vehicles and Motorsports, wouldn't say if the COPO is a profitable venture, but noted the fire-breathing dragster raises the image of Chevy and Camaro. "It makes sense for our business from a number of perspectives," he said. The first COPO Camaro, a Courtney Force-styled racecar that was revealed in November at the SEMA Show in Las Vegas, hammered for $300,000 at the Barrett-Jackson auction last month. The proceeds went to the United Way. Campbell said low COPO production keeps interest high. Enthusiasts can also build their own COPOs by buying a rolling chassis and a crate motor, though those are not viewed by collectors in the same manner as GM factory-built creations. The COPO Camaro's V8 is one of several competition engines designed, built, and validated at the GM Performance and Racing Center. The Corvette C7R's 5.5-liter V8 and the Cadillac ATSV.R's 3.6-liter twin-turbo V6 are two more. Chevy calibrates and conducts dynamometer testing on its 2.2-liter V6 for IndyCar and performs design work on its NASCAR V8 at the facility, which existed previously at another location in Michigan.

Chevy reveals new IndyCar aero package

The IndyCar Series is not one that demands its participating teams and automakers to design their own chassis as they do in Formula One, but for this season, the organizers have opened it up to allow for custom aero packages. What you're looking at here is the new look of the chassis to be fielded by teams running under Chevy power. Based on the Dallara DW12 chassis – introduced three years ago and named after the late Dan Wheldon – Chevy's new package is designed for road courses and short ovals, with the speedway configuration to be revealed later. The kit features new wings front and rear and more sculpted side pods. It's also got new wedges at the back to envelop the otherwise open wheels that are a hallmark of Indy racing, a more streamlined engine cover and bigger rear bumper pods. The new package will debut at the Grand Prix of St. Petersburg that will kick off this year's championship in Florida on March 29, followed by the road-course grands prix in Louisiana, Long Beach, Alabama and Indianapolis before the new package needs to be ready for the Indy 500 late in May. Half of the teams on the starting grid this season will be running under Chevy power and are expected to use this new aero kit, with the remaining Honda teams slated to run a different package of their own. Chevrolet Debuts All-New 2015 IndyCar Aero Package Chevy-developed bodywork delivers improved aerodynamics 2015-02-17 INDIANAPOLIS – Chevrolet-powered racecars in the 2015 Verizon IndyCar Series will feature Chevrolet-developed aero packages. Chevrolet introduced the road course/short oval body design today at the Indianapolis Motor Speedway. It is distinguished from the previous racecar with new front wing elements, sculpted side pods and a new rear wing. A speedway configuration for the aero kit, designed for high-speed ovals, will be introduced ahead of its competitive debut at Indianapolis in May. "This is an important milestone in Chevrolet's involvement in IndyCar racing," said Jim Campbell, General Motors U.S. vice president of Performance Vehicles and Motorsports. "We focused on developing an aerodynamic package that delivers an balanced combination of downforce and drag, along with integrated engine performance. It's a total performance package." The new Chevy road course aero configuration delivers greater aerodynamic performance than the previous design.
